SARGENT introduced the standalone Profile Electronic Access Control Series Locks in 2001. These electro-mechanical locks can control access electronically using keypad, Radio Frequency (RF) technology and proximity for up to 2,000 users. These locking devices are UL Listed for use on fire doors. The Profile Series is available in three configurations: cylindrical, mortise and exit device.
For the purpose of this article, we will install a cylindrical version of the SARGENT Profile Lock using the new Major Manufacturing HIT-136 onto a non-fire rated interior wood door in a large facility. The Profile Series cylindrical lockset is based on an ANSI/BHMA Grade 1 SARGENT 10 line mechanical lock.
To simplify the installation of the SARGENT Profile Series Cylindrical Locks, Major Manufacturing has developed the HIT-136 Drill Guide, which provides pilot hole locations to simplify the door preparation.
The Major Manufacturing HIT-136 Drill Guide is designed to locate the cross bore openings, wire slot (wood door only) and screw openings in a wood or metal door. A standard 2-1/8” cross bore opening having a 2-3/4” backset is used to locate the drill guide.
To install a SARGENT Profile Series cylindrical lock:
Step 1. Place the front and back plates of the HIT-136 onto the door faces.
Step 2. Install and tighten the hex bolt using the supplied 5/16” wrench. Tighten the bolt until the leaves do not move. Do not over-tighten as the faces of the door can be marred.
Step 3. Use a 5/16” drill bit and drill the two through-bolt holes. These holes are located at the 12 and 6 o'clock positions. Drill these holes from both sides.
Step 4. Drill the three 1/4” diameter holes from both side of the door. They are located at the top, nearest the top and the bottom of the drill guide. The top and bottom holes are for the escutcheon posts 1/2” diameter). The third hole is for the wire run (1-1/2” diameter). These holes will be enlarged once the drill guide is removed.
Step 5. On the inside of the door, drill two 1/4” diameter openings approximately 5/16” deep. These openings will be connected, providing a wire run underneath the inside lock mounting rose. Important: Drill these two openings only on the inside of the door.
Step 6. On the inside of the door, drill the two 5/32” diameter openings to a depth of 1/4” for the anchor lugs on the left and right side of the 2-1/8” cross bore opening.
The door preparation holes have been drilled.
Step 7. Remove the HIT-136 from the door.
Step 8. Use a 1/2” diameter drill bit to enlarge the top and bottom 1/4” diameter holes to accommodate the mounting posts. To ensure an accurate hole, drill half way through both sides of the door.
Step 9. Use a 1-1/2” diameter hole saw to enlarge the remaining 1/4” hole beneath the top 1/2” drilled hole. This opening is used to run the ribbon cable and the ground wire from the exterior assembly into the interior assembly.
The next step is to accommodate the wires from the cylindrical lock body. If the door is wood, chisel out a slot between the two 1/4” diameter openings drilled in the interior side of the door. The slot should be cut deep enough that the wires do not cause the lock to tilt. If the door is metal, cut a slot between these two holes.
Step 10. Modify the interior door face to accommodate the wires from the cylindrical lock body.
The next series of steps are to install the Profile cylindrical lock onto the door.
Step 1. Prepare the lock to accommodate the hand and thickness of the door. The first notch on one through-bolt is used to locate the lock body for a 1-3/4” thick door. The second notch is for a 2” thick door.
Step 2. Install the latch into the door edge and start the two Phillips head screws.
Step 3. Feed the wires and the lock body through the 2-1/8” diameter cross bore opening, making sure it engages the latch unit.
Step 4. Places the wires into the slot and secure the cylindrical lock to the door using the inside rose spring assembly and the two Phillips head screws.
